N1114LS1 to N1114LS18 5. Calculating V T using ABCD Coefficients The on-state characteristic I T vs. V T, on page 7 is represented in two ways; (i) the well established V o and r s tangent used for rating purposes and (ii) a set of constants A, B, C, D, forming the coefficients of the representative equation for V T in terms of I T given below: V T = A + B ln ( IT ) + C IT + D IT The constants, derived by curve fitting software, are given below for both hot and cold characteristics. The resulting values for V T agree with the true device characteristic over a current range, which is limited to that plotted. 5 C Coefficients 15 C Coefficients A.3544 A -.1888971 B.397938 B.99696 C 4.894957 1-4 C 5.6675 1-4 D -.348948 D -.33749 5.3 D.C.
